Abstract
This invention relates to a support for carboxylic acid components of animal feeds
said support comprising beet pulp. Beet pulp, unlike conventional supports such as
silica, perlite, vermiculite etc, is readily digestible by the animal. Beet pulp is a a
nutritionally beneficial and absorbent support which is not only naturally occurring
but is also part of conventional animal feeds.
Description
This invention relates to a support for acids and salts, especially for
carboxylic acids and their salts, which are used as feed components in animal feeds.
It is well known that acids and salts are an important component of animal
feeds due to their inherent fungicidal, bacteriocidal and other preservative
properties. However, such acids and salts, especially the carboxylic acids and their
salts when they are in the liquid form are not easy to distribute as such uniformly in
an animal feed. They not only have the problem of wetting the feed thereby
adversely affecting the free-flowing properties of the animal feed but they also have
the ability to corrode the distribution and storage vessels and are a risk to the
operatives handling such acids or salts.
In order to overcome these problems, the use of adsorbent solids of the
desired particle size range has been suggested in US-A-3846567. According to
this document, liquid acids are transformed into solid powders by adsorbing such
acids on the surface of a highly dispersed solid substance of small particle size (less
than 10 microns). Such solid substances may be selected from oxides, activated
charcoal, perlite, plastic powders, bentonite, silica, alumina, silicates, aluminates or
peat. Similarly, US-A-4199606 suggests the use of vermiculite and perlite carriers
for propionic acid used as a preservative for various agricultural crop products and
by-products thereof such as eg animal feeds and cereals. Again GB-A-1389588
suggests a free-flowing, powder form of an agent for preserving mixed feedstuffs
and cereals, the agent comprising propionic acid and a highly dispersed synthetic
silicon dioxide and/or silicate having a particle size of less than 500 mµ and a
surface area of 100-500 m2/g. Also suggested in the prior art is the use of foamed
and granular substances or synthetic resins for impregnation thereof with eg the
acids. However, this raised more problems than it solved. For instance, such
resins had detrimental effects on the digestive tract of the animal; it affected the
quality of the meat from the animal fed in this manner because of the inevitable
leaching of softeners, plasticizers etc from the synthetic resin; such resins adversely
affected the pH value (highly acidic) in the digestive tract; the indigestibility of such
resins and the consequent dispersal of the animal dung in which the resin granules
were virtually impossible to decompose; and the lack of water absorbency of such
resins when such dung is used as fertilizer. Some of these problems were
overcome by the method described in US-A-4310552 which suggests impregnating
indigestible but naturally occurring supports such as expanded perlite or
vermiculite with various animal feed components and then mixing/blending such
impregnated supports with conventional animal feeds. It is possible to visualise the
use of such indigestible, naturally occurring supports for impregnation thereof with
carboxylic acids. Whilst this overcomes the problems of handling free/liquid acids,
it adds to the cost of the animal feed and at the same time has the disadvantage that
the support itself has no nutrient value to the animals fed. Also, such supports
have the disadvantage due to their high porosity of being highly water adsorbent
thereby increasing the demand on the water fed to the animals. Thus, the use of
such indigestible supports result in the increase in the volume of the animal feed
and the amounts consumed by the animals without having any particular
nutritionally beneficial effect.
It has now been found that such problems may be mitigated by using a
nutritionally beneficial and absorbent support which is not only naturally occurring
but is also part of conventional animal feeds.
Accordingly, the present invention is a support for carboxylic acid
components of animal feeds said support comprising beet pulp.
Beet pulp is a conventional and regular animal feed component. The
commonest source of beet pulp is as a by-product of the beet sugar industry and is
a relatively inexpensive material costing about £0.08/kg. However, beet pulp has
never been used as a support for carboxylic acids and/or salts, especially when they
are in liquid form either as such or as solutions thereof for use in animal feeds.
Beet pulp is capable of absorbing organic acids and/or salts which are liquids as
such or solutions thereof in a solvent to form a free-flowing product.
Beet pulp can be impregnated with the carboxylic acids, salts of carboxylic
acids (whether partially or fully neutralised), or solutions of such acids and salts
used as preservatives in animal feeds. Beet pulp may be impregnated with the
carboxylic acid/salts or solutions thereof eg by spraying the acid itself, when in
liquid form, or an aqueous or alcoholic solution thereof or a salt thereof on the beet
pulp support. The acid and/or salt is absorbed slowly and may take from 1-30
minutes depending upon the viscosity of the acid and/or salt solution used.
Specific examples of such acids include at least one acid and/or salt of a C1
to C12 carboxylic acid, which may be saturated or unsaturated, straight or
branched chain and has at least one carboxyl group, especially selected from formic
acid, propionic acid and salts thereof. Where salts of the carboxylic acids are used
these are suitably ammonium, sodium and potassium salts.
The amount of acid and/or salt that can be incorporated in the beet pulp is
suitably in the range from 1-75% by weight, preferably from 5-70% by weight
based on the total weight of the beet pulp and the acid/salt. In other words, the
amount of beet pulp on which the carboxylic acid or salt thereof is supported is
suitably in the range from 30% to 99% by weight based on the total weight of the
support and the acid and/or salt.
Laboratory tests have shown that a mixture containing 70% by weight of
beet pulp and 30% by weight of propionic acid can still produce a free-flowing
product. Equally free-flowing is a mixture of 50% by weight beet pulp and 50% by
weight formic acid (as an 85% w/w aqueous solution). These mixtures can be used
in a manner similar to any other organic acid or salt on a carrier/support for the
preservation or for fungicidal/bactericidal protection of animal feeds. Examples of
two typical animal feed formulations which contain beet pulp are shown below:

Beet pulp has nutritional value and is a normal animal feed component
when compared with other conventional carriers/supports such as eg perlite,
vermiculite and dried clays. Beet pulp has inherent nutritional value when
compared with conventional carriers/supports. Beet pulp is very cost effective
when compared with conventional carriers/supports. Beet pulp does not result in
animal excreta in which the carrier support is not naturally decomposable or does
not easily spread when used in fertilizers. Beet pulp is more economical when
compared with conventional carriers.
